Do I have any potential in comedy? (link to my videos)?

Well at least 4-5 times a day I hear people say that im funny or something like that.. and some people have even encouraged me into getting into a career as acting or something along those lines. I kind of need an opinion of people I dont know personally other than people on youtube who leave dumb comments:
heres some of my stuff so far

and then this, isnt as much of me making up funny stuff on the spot, but acting, and I know that the other kids are laughing but I can keep a straight face for that (watch the my new haircut video too that im responding to

I know that getting a job in acting is almost as hard as winning the lottery, but I hear it so much that I had to ask.

I noticed that you're in Detroit, so am I, I also noticed the name Michael Barrett listed on your Chinese Restaurant call...This may sound strange, but does he have a younger brother named Christopher?

If so, then I'm their uncle who hasn't seen them in years...please e-mail me and let me know if this is the same Michael Barrett.

Thanks.
